    Ya forgot to mention that of those 27253 messages (just using your count
as an example) damn nead close to 0 are likely to reach an infected host since
SWEN spoofs and lots of C-R systems fall for it.

    BTW, just curious how you detect SWEN before the MTA gets it?  Usually
mine is post-contact on at least one occasion.  After that it was firewall but
now it is just drop on a RCPT test.  Hrm, should make it a HELO test.  :/
